Schilling,strasse, Reinickendorf ,L West, nearv Berlin, Germany, haveinvented new and useful 'Improvement-s in vGras and' (,)xygenv Burners',of which the lfollowing is .a specifi;

glhejpresent.-'inyention relates to gas and .or-.'-ygen burners inwhichtheoxygen supplied athigh pressure; sucks' the `gas from anup-Awardly-tapering annular chamber adapted the' shapeof. the oxy' 'n nozzleandfcon- 'Veys itintov the c annel'. In accordance v'witlifthe inventionon the mixed in additionjby ltheir either hitting againstgthe cover oranenlarged'burnerhead,

y,the.orifices foi' tHeM-,mixture being arranged. near'rthe outside edge'of theburnerehead, or

as'uitable number' or. coils are arranged :the mixing channel, whichmay'also form turns -or the like running in an' opposite direction,

and a `known 'conical face isarrangedat the' l coyer ofthe head oftheburner; this face conduct-s the gases ,to the openings of-the"'burnereheam in which. openings tubes of a fis v'niatei'ial whichconducts heat as. badly as ,possible-,1. or 'which' is insulating andiire'- proof, may -be'preferably attached, order "to produce anmsulating' layer of air between .the upperm'out-.h of the tubes, whichnow forms the burning surface, and the lower parts of the' burner orburner-head and mixing' channel. This layer of air is continu-l ouslyrenewed, lows round the tubes-and thereby cools them, and tends upwardtothe flame with considerable energy.

In order that the vinvention may understood reference is made to theaccompanying drawing in which embodiments are represented by .way ofexample, and in whichz- Figure 1 is a Vertical longitudinal sectionthrough one form of burner, and Figs; 2 and 3 show details of thesame,Fig. 3 being a vertical section through the upper part of theburner-head, Fig. 4 is an elevation part-ly in section of a' modiiiedform of burner, whereas Fig. 5 is a diagram showing that the windingss'pineatien of Letters Patenti Application ined February 27, 190s.seria;-` No. 418,167;

ofthe mixing channel can also be replaced by anotheiiorm, for example bya plurality of turns or uthe like ruiming in opposite directions. j

v Referring to thev drawing, the burner car- :riedbythe socketsgt of adouble stop-cock lor the like consists of a case 'c (Fig. l), the linnerwall of which corresponds in the usual ,manner with the oxygen nozzle Zirunning'to' 65 :a point,- so that an annular chamber d (Fig. 1) isformed tapering upward and inclosing the nozzle, which chamber opensinto a narrow mixing channel h of' suitable length. The mixing channel hopens into a burner- 70 hea'd'e having an Aenlarged mixing chamber f(Fig. 1), from which the 'mixture of gases. iio'ws through oriiices m inthe cover of the burner-head e (Fig. 3). Gas is conducted into the'chamber d surrounding the nozzle by 75) means of 'a pipe y (Fig. l).The pointed oxygen nozzle b in the case c has been provided with alongand narrow outlet channel i (Fig. 2) which is enlarged-at 7c at its end.

Oxygen .flows through lthe opening fi of vl 'nozzleb into the tapering'chamber `and sucks gas from this c amber into the mixing channel'h, 'andsince thenozzle-channel t' is i .enlarged atlc at its upper end, thestream of outside edge of its orifice and penetrate into 4the 'otherstream of'gassurrounding it, on which' it exercises a suction-effect inthe manner of a jet-blast. Both gases which-mixv to someextent. in thechannel k enter into thev enlarged'cha'mberf, (Fig. l) reboundon theroof or cover of 'tlielhead e, and whirl around', whereby the mixing ofthe same is perfected. The gases then pass out through many ori= of theburner-head. By this arrangement l it is possible to intimately mix thetwo gases within 4the burner without hating to fear an explosion, and,with regard to the sha e of flame and its heating power, a favorab e re-100 sult is obtained with asmall consumption of oxygen.

The other form of burner represented by way of example in Fig. 4 is thesame, as regards its arrangement, up to the mixing 10-5 channel h (Figl) ofthe casing c which is not represented. The head of the burner,here. denominated o, has been constructed in another manner however, andbetween it and j the' 'previously mentioned mixing channel h ofthecasing c which is not shown there is l' serted or arranged a fairly longextraen/iii,

oxygen Acan spread out, immediately 'at the 85 u iices, at the outsideedge of the top or cover mitra, a of the mixing channel which has at m aplurality of coils, or instead of the same a inuniber of turns or thelike running in con-.-

trary directions (Fig. The cover of the burner-head o is conical yin thecenter of the orifices at its edges, whereby'the'gases are Conducted tothe orificesas indicated by the arrows. In these orifices there areattached tubes j) of suitable length which preferably consist of aninsulating iireproof material or one which conducts lheat badly.4 Inthis form of construction (Fig. 4) the gases are vmixed sti-ll moreintimately in the'long e-X- tension n, mfnvof 'the mixing channel, andthe burning surface or the' place where the very hotliiame is formed hasbeen removed by ybetween thev tubes, flows vround the latter and` coolsthem, a new insulating layer of air isproduced which is, uninterruptedlyrenewed and which energetically vascendsA toward the flame, and thislayer of air keeps off the `heat of the flames radiated from the burner:But also a considerable quantity oi-4 fresh air is su plied in additionto the flames'. themselves W ich not only flows around the tubes p, butalso the individual i'lamesflow- --ing around thelowerV portion of thelatter .until they .unite into one single rilame.

f Lastly however, the case c is kept almost perfectly oo ol on accountyof a fairly long'eX- tension n, m, 'n of the vmixing channel beinginserted, because the `heat conducted .back -ward has traversed uptothat cinta fairly i long path cooled by air, Where y the otherf ber, ahollow burner-head having an internal Wise injurious effects areprevented.

What I claim as my invention and desire to secure by Letters Patent' isj 1. In a burner. ofthe type described, the combination, with a sto.-cock having two sockets, of a conical nozz e having an orificeenlarged at itspoint connected with, one

f socket, a case on said nozzle. connected with the other socketinclosing an annular conical .Y

3. In a burner-of lthetype described, the combination with a sto -oockhaving .two sockets, of a conical nozze having an orifice' enlarged atitsl point connected with one socket, a case on-said nozzle connectedwith the other socket inclosing anannular conical chamber `around saidnozzle and providing a mixing channel4 connected with said chamber, ahollow, enlarged burner-head having orifices arranged'near itslperiphery on said case, and a pluralityoftubes forming the mouth vofthe burner in said orifices in said burner-head, the latter orificesbeing ar- 'ranged at such a distance from one another that an insulatinglayer-of air cany cool the tubes, as set forth.
